If there's one thing the industry will remember about Supergiant Games' Bastion, chances are it'll be its audio. The game's rich, ethereal score and iconic narration gave the game a very unique tone, and went a long way toward establishing its striking aesthetic.

And at the 2012 Game Developer Conference, Bastion's audio and music designer, Darren Korb, discussed the ins and outs of how he made the game's sound stand out from the pack.

Of course, there were plenty of factors at play, but one of the game's most successful elements, Korb explains, was its narration. It allowed the game to tell its story without ever interrupting gameplay, and as it turns out, this iconic feature only came about due to a stroke of luck.

When he began working on Bastion, Korb happened to live with his childhood friend and actor Logan Cunningham, and his voice acting skills helped inspire Korb to give in-game narration a shot.

He explains, "[Supergiant was] kind of experimenting with different narrative techniques that allowed us to give the player a story without making them stop and doing the wall of text thing...And the fact that Logan was a talented actor and was my roommate made me think, 'Well, hey, let's just try narration!'"

After just a few voiceover sessions, the team knew it was the right direction to take. As the project went on, Korb learned even more about working with game audio, as he outlines in the above presentation.
